Abstract
"Perfecting tensioning device", characterized in that it is constituted by a support part that is coupled to the body of the drive motor through two screws that pass through it, which comprises a cylindrical pocket whose axis is substantially perpendicular to the axes of the holes for step of the screws, in whose pocket a bolt is held by an antagonist spring that is collected between the head of the bolt itself and the bottom of the pocket, from which through an orifice protrudes the body of the bolt at the end of which is established a threaded projection of smaller diameter.
